Surveying, GIS, & Remote Sensing POST TEST

Question 1

It is a type of surveying that treats the surface of the earth as flat surface. The spheroidal shape is neglected, with regard to horizontal distances and directions.

Answer 1

Plane Surveying

Question 2

This surveying made to determine the length and direction of land lines and to establish the position of these lines on the ground.

Answer 2

Boundary Surveying

Question 3

This is a special form of theodolite that has a stadia diaphragm and an anallatic lens. This eliminates the need for a chain because the distance can be calculated using the diaphragm.

NOTA
Plane table
Tachometer
Total Station

Answer 3

NOTA

Question 4

It is a graphic representation of the Earth’s natural features; artificial or human-made structures; or observable facts, occurrences, or circumstances; usually drawn on a flat surface or in a two-dimensional (2D) medium.

Answer 4

MAP

Question 5

These are imaginary lines that show the elevation (the vertical distance above or below sea level) and relief (shape of the terrain) of the different features on the surface of the Earth.

Answer 5

CONTOUR

Question 6

It describes the vertical datum where elevation/height values are referenced and not from the base of mountains or hills.

Answer 6

Mean Sea Level

Question 7

The acronym GIS stands for _

Answer 7

Geographic Information System

Question 8

These are numbers that describe the position of a certain feature on Earth. They are used to define the spatial location and extent of geographic objects.

Answer 8

Coordinates

Question 9

It is a process in which you model problems geographically, derive results by computer processing, and then explore and examine those results.

Answer 9

Spatial Analysis

Question 10

Who first coined the term geographic information system (GIS) that created the first computerized geographic information system in the 1960s while working for the Canadian government—a geographic database still used today by municipalities across Canada for land planning?

Answer 10

Dr. Roger F. Tomlinson

Question 11

Who developed the ArcGIS?

Answer 11

ESRI

Question 12

It is a model that represents a simplified view of physical entities, the roads, mountains, accident locations, or other features we wish to identify.

Answer 12

Data

Question 13

These set of layer organizes the spatial and attribute data for a given set of cartographic objects in the region of interest.

Answer 13

Thematic Layers

Question 14

_____ data are used to record the nonspatial characteristics of an entity. It is also called item or variable.

Answer 14

Attribute

Question 15

An attribute that provides descriptive information about an object.

Answer 15

Nominal

Question 16

An attribute that implies a ranking or order by their values. It may be descriptive, such as high, mid, or low, or it may be numeric.

Answer 16

Ordinal

Question 17

It describes the world as a set of point, line, and area features.

Answer 17

Vector Data

Question 18

It is based on grid cells and represent the world as a “checkerboard,” with uniform values within each cell.

Answer 18

Raster data

Question 19

It is the process of defining exactly where on the earth’s surface an image or raster dataset was created

Answer 19

Georeferencing

Question 20

The smallest unit of information in an image or raster map.

Answer 20

CELLS/PIXEL

Question 21

Are common vector spatial data format that uses an index to link files and were originally developed by ESRI, inc., as a way to store point, line, and polygon features.

Answer 21

Shapefiles

Question 22

The science of obtaining the physical properties of an area without being there. It allows users to capture, visualize, and analyze objects and features on the Earth’s surface.

Answer 22

Remote sensing

Question 23

It is a remote sensing method that uses light in the form of a pulsed laser to measure ranges (variable distances) to the Earth.

Answer 23

LiDAR

Question 24

It involves making sounds and listening to the way they bounce off objects. The echoes provide very useful information about the objects.

Answer 24

Sonar

Answer 28

415,000, 6,450,000

Question 29

It is a type of GIS maps that incorporate color-coded systems to display numerical density in a given area. It is an effective way to easily relate numerical data when dealing with a large amount of data.

Answer 29

Heat Maps

Question 30

It indicates the relationship between the distance measured on the map and the actual distance on the ground.

Answer 30

Scale
